Research on Capacity Configuration of Wind Storage Hydrogen Production Plant Considering “Source-Load” Double Disturbance

Hydrogen production from wind power is an important method to solve the problem of wind abandonment and improve the utilization rate of wind power. However, the “source” turbulence caused by unstable wind speed and the “load” turbulence caused by sudden load change will adversely affect the stable operation of power-to-hydrogen system and the grid connection stability of wind farm. To solve this problem, a synergistic control strategy between supercapacitor and power-to-hydrogen system is proposed. The strategy is based on the Ensemble empirical mode decomposition algorithm. By making the supercapacitor stabilize the high-frequency component in the turbulence of “source-load”, the stability of power-to-hydrogen system is improved, and an optimal allocation method of supercapacitor capacity suitable for the control strategy is proposed. Finally, the effectiveness of the strategy is verified by Simulink simulation.
